A CORPORATION OF NEW YORK ADJUSTABLE SHELF SUPPORT Application filed April 26,

This invention relates to adjustable shelf supports and has for'its general object and purpose to provide an improved mounting of the adjustable supports for the shelves of bath room cabinets or other structureswhich will provide means enabling the proper adjustment to be easily and quickly made and wherein the support will be rigidly and securely retained in its adjusted position against the possibility of accidental displacement. 1 It is another important object of the invention to provide means for adjustably mounting shelf supports whereby the use of separate adjustable pins, screws or other analogous elements may be entirely dispensed with.

It is also an important practical object of my invention to provide a shelf supportand in position on the wall of the cabinet, which may be inexpensively fabricated in the form of comparatively simple sheet metal stamp- ,ings and easily and quickly applied in its attached position to the wall of the cabinet. With the above and other objects in view, the invention consists in the improved adjustable shelf support and in the form, construction, and relative arrangement of its several parts, as will be hereinafter more fully described, illustrated in the accompanying drawing, and subsequently incorporated in the subjoined claims.

In the drawing, wherein I have disclosed one simple and practical embodiment of. my present invention, and in which similar ref erence characters designate corresponding parts throughout the several views,

Figure 1 is a fragmentary perspective View of a cabinet showing my improved shelf supporting means applied thereto;

Fig. 2 is a vertical sectional View taken on the line 22 of Fig. 1; i

Fig. .3 is an enlarged fragmentary elevation, and j I Fig. 4 is a horizontal sectional view taken on the line 4-4 of Fig. 3. v V For purposes of illustration, in the accompanying drawing, I have shown my invention'as applied to abath room cabinet of the means for adjustably mounting the same 1930. Serial No. 447,525.

sheet metal, a part of the, cabinet body being shown at 5. To each side wall of the cabinet on the inner face thereof and in suitably spacedcrelation to the rear wall of the cabinet at its front open side, the vertically extending guides '6 for the shelf supporting members are suitably attached, as 'for instance by means of the screws indicated at 7 Each of these guides consists ofa sheet metal strip of suitable width extending substantially for the entire distance between the top and bottom walls of the cabinet body.

This strip is suitably stamped or pressed to provide therein in spaced parallel relation to each of its longitudinal edges, a single longitudinal corrugation 8. Betweenthese corrugations and at vertically spaced points,

tongues 9 are struck from the metal strip,

said tongues projecting from the plane of the strip in the same direction as the ribs or beads formed'by the corrugations 8 but being offset for a distance only substantially equivalent to the thickness of the metal.

These tongues remain integrally connected at their upper ends with the body of the metal strip by the angular offsets 10, while their lower end edges are spaced above the edges of the openings formed in the plate by said offset tongues to provide the slots indicated at 11.

It will be evident from the above description that when the metal strips 6 are attached to the walls of the cabinet as seen in Figs. 1 and 4 ofthe drawing, with the convex sides of the beads formed by the corrugations 8 in 5 contact with the cabinet wall, the opposite vertical edges of said strip as well as the intermediate portion thereof between the cor rugations 8 are spaced from the wall of the cabinet. The tongues 9 are likewise slightly spaced from the inner face of the cabinet wall. Upon these attached metal strips, the shelf supporting members are slidably and adjustably mounted. v

Each shelf supporting member is also formed from a sheet metal stamping having the angularly related flanges 12 and 13 respectively, the flange 13 at one of its ends having an upwardly projecting stop lug 14. The flange 12 of the supportingmember has spaced angularly bent lips 15 struck therefrom and the opposite edges of the plate 6 are engaged between one side of the flange 12 and the ends of the lips 15 which are positioned in spaced parallel relation to said flange. Thus, it will be understood that the cooperative engagement of the angular lips 15 with the opposite vertical edges of the metal strips 6 serves to slidably guide the movement of the shelf supporting member relative to said strip and also to prevent any angular movement of the supporting member relative to said strip.

The flange 13 projects laterally and inwardly from the upper edge of the flange 12 and the lower edge of the latter flange-is centrally provided with a downwardly extending arm 16, the lower part of which is of such width that it will readily pass through one I of the slots 11. The lower extremity of said arm is laterally oflset as shown at 17 towards the strip 16 and the end edge ofsaid offset portion of the arm is preferably beveled as at 18' y The distance between the ends of the lips 15 and the face of'the plate 12 sufficiently eX ceeds the thickness of the metal plate 6 so that when the offset end of the arm 16 is not engaged through one of the slots 11, there is suflicient play between the flange 12 and the strip 6 to permit the offset end of arm 16 to sliderfreely on said stripwithout excessive friction. Thus, the shelf supporting member may be freely moved vertically upon the strip 6 and when disposed in the desired adjusted position with the offset end of the arm 16 opposed to one of the offset tongues 9 of the strip 6, said lower end of the arm will move laterally against the face of the tongue 9. By then forcing the supporting member downwardly so as to cause the beveled lower edge 18 of the arm 16 to engage the edge of the slot 11, said end of the arm-will be s run laterall the ton ue 9 ieldin to a p c: 7 D b in its adjusted position'with respect tothe' metal strip 6. a I I After both of the supporting members have been adjustedin the manner explained, to the same vertical positions as the respective strips 6, theendsf of t 1e shelf 19 which may be of glass or. other material arethen positioned upon the flanges 13, the stops 141 on the front end of said flanges,prevent outward sliding movement of the shelf through the open side structed, reiiable and serviceable device for the intended purpose. The shelf supporting members and the metal strips whereby they are attached in applied relation to the opposite side walls of the cabinet, at all times remain assembled so that there is'no possibility of the shelf supporting members being completely removed and misplaced or lost. Nevertheless, the proper adjustment'of these shelf supports can be very easily and quickly nade, and without requiring the manipulation'of pins, screws or other connecting or fastening elements. It will further be appreciated that since the several parts are in the form of very simple sheet metal stampings, my invention may be produced on a quantity production basis at very low cost and applied'as an accessory to bath room cabinets and similar structures, without materiallyincreasing the selling cost thereof.

In such cabinets, means is provided for hinge ,ly mounting the door at the right hand side of the cabinet. t sometimes occurs however, that owing to the architecturalfeaturesof the buildin structure, it is necessary to mount the cabinet so that the door will be hingedly supported at the left hand side thereof. With my shelf supportingdevice as above described, the cabinet may be readily reversed for this purpose, it being only necessary to reverse the guide plates 6 so that the slots or openings 11 will. be at the lower ends of the tongues 9; parent that in stamping these guide plates, if desired, the tongues 9 may remain integrally connected with the plate at their opposite side edges as well as at their upper ends.

In the foregoing description, and the ac I claim: i V
